trekkie, to sign up you ask me. That was implied from my post (at least I thought it was).
We cannot offer anything but a subdomain and directory. Our hosting does not have add-on domains, I never saw any need for them with us. If you want something different,
dot.tk is a free. You also could set up your pay domain to forward here, most won't notice. This is designed to be free hosting. Sharing the SSCentral domain name is an honor I believe, it means your site fits a certain standard of quality. Many sites have hosted "affiliates." Look at
ticalc.org. Their hosted sites are proud of being part of ticalc.org. If it's not your style I can't help you, your style should have everything to do with your site and content and less with your URL. If you want great free hosting, regardless of the URL I think you should take it.
Also BlueSmudge, I believe I told you before you got way too much for what you need... even with those videos you still don't use 1/5 of what you have. We paid $30 a year and we still get more than we need by a long shot. Though it is nice that you're helping out by giving some away. You shouldn't need to waste your money on hosting when you should be spending it on what really matters, water guns!
